SILO-DOOR-ATTACI-IING MEANS.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed February 2, 1914. Serial No. 816,128.

To all whom it may concern:

Be it known that I, JULIUs H. SOHLAFLY, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented a new and useful Silo- Door-Attaching Means, of which the following is a specification.

My invention relates to improvements in the construction of doorattaching means, and while applicable to doors of various kinds and forvarious purposes, is more particularly adapted for silo doors.

The objects of the invention are, to generally improve the attachingmeans for doors of the character mentioned to provide a door attachingmeans especially adapted for silos and the like, which will be strongand durable, easily operated, capable of producing a substantiallyhermetical closure and involving few and simple parts.

These objects, together with other objects which will be apparent tothose skilled in the art, may be attained by the constructionillustrated in the accompanying drawings, although the invention may beembodied in other forms, the construction illustrated being chosen byway of example.

In the drawings Figure 1 is an elevation of a portion of a sectionalsheet metal silo provided with a door embodying my new invention. Fig. 2is a perspective View of a portion of said silo and the door frame. Fig.3 is a perspective view of the door its-elf. Fig. 4 is a perspectiveview of one of the locking wedges. Fig. 5 is a perspec tive view of oneof the hinge wedges. Fig. 6 is a perspective view of one of the lockingwedge housings. Fig. 7 is a vertical sectional view taken on the line 77of Fig. 1. Fig. 8 is a horizontal sectional view taken 011 the line 8-8of Fig. 1, showing the door in sealed position. Fig. 9 is a similar viewshowing the door in unsealed and partly open position.

Throughout the several views similar reference numerals indicate similarparts.

More specifically describing the construction disclosed in saiddrawings, the numerals 1, 2, 3 and 4 indicate several sheet metalsections connected together at their edges and forming a portion of thewall of the silo.

A door-frame formed of sheet-metal and comprising the flanges, 11, 12,13, 14L and 15 is connected to the sections 1, 2, 3, and t by means ofthe bolts 8 and 18.

The sheet-metal door provided with the body 19 is adapted to close theopening 20 of the door-frame when shut against the flanges 11, 12, 13.

Connected to the body of the door by means of the bolts 25 are two,vertically spaced bars 26. Intermediate the side edges of the door saidbars may be bent outwardly from the body 19 to form ladder rungs, asclearly illustrated in the drawings.

For the purpose of hinging the door to the frame the free ends of thebars 26, at one side of the door, hereinafter called the hinge side, areprovided with integral knuckles 27 adapted to receive the hinge wedges28, as presently described. Connected to the dooni'rame at the hingeside of the door by means of bolts 29 are the hinge wedge housingsformed from sheet metal and providing a lower wedge loop 30 and an upperwedge loop 31, said lower loop 30 extending outwardly from thedoor-frame a greater distance than the loop 31, and a knuckle receivingopening 32 adapted to receive the knuckle 27 of one of the bars 26beingdisposed between said lower and upper loops. The hinge wedges 28extend through the loops 30, knuckles 27 and loops 31 forming hinge pinsupon and about which said knuckles are adapted to rotate. The largerends of said hinge wedges are downwardly disposed, and some means, asthe rings 33, extending loosely through aportures in the upper, smallends of said wedges should be provided to prevent said wedges fromfalling downwardly so as to become entirely detached from the wedgehousings. It will be readily understood that the wedges 28 may be drivenupwardly so as to force the knuckles 27 toward the doorframe, and thusfirmly seat the hinge side of the door against the flanges of the saidframe. At the same time it should be noted that regardless of the factthat the hinge wedges have been driven upward until they tightly engagethe loops 30 and 31 so as to produce th sealing action just describedthe door will usually be free to swing open upon said wedges, acting ashinge pins, even without driving said hinge wedges loose, as the initialmovement of the knuckles 27 upon said hinge wedges will have a tendencyto dropping entirely out only by the engagement of the rings 33with theupper loops 31. For the purpose of providing means whereby to lock andhold the door in closed position the bars 26 are provided with free.

ends extending beyond the free-edge of the door and constituting lockingtongues 3% on the locking side of the door. Said tongues 3e are adaptedto approach the door-frame when the body of the door is seated againstthe flanges of the said frame. For the purpose of locking said tonguesin said position and producing a clamping action adapted to thoroughlyseal the door, locking wedge housings 35, similar to the hinge wedgehousings heretofore described, are provided. Said housings 35 aredisposed with their larger wedge loops 30 above their smaller wedgeloops 31 the tongues 34 being adapted to be received between said loops30 and 31 and locking wedges 36 are provided and adapted to be arrangedwithin the loops 30 and 31 in front of the tongues 34 to draw saidtongues toward the frame and hold the door in locked position. It willbe understood that the wedges 36 are disposed with their smaller endsdownwardly and that, in order to open the door, said wedges are entirelyremoved from the housings 35. In order to prevent said wedges from beinglost, therefore, I prefer to provide soft flexible connections, such asthe chains 37 connected to the silo and to the rings 38 in the largerends of said wedges. In closing and sealing the door the wedges 36 maybe driven downwardly with a hammer or other implement, as the wedges 28are driven upwardly and in order to unseal and open the door it is onlynecessary to drive said wedges by upward blows on the lower, smallerends, as will be readily understood. Attention is here called to Figs. 8and 9. Fig. 8 illustrates the door in the closed, locked position, thewedges 28 and 86 holding the door firmly pressed against the flanges ofthe door frame and Fig. 9 illustrating the wedges 36 removed and thedoor swung partly open, the hinge wedges 28 having fallen to theirlowest position and thus not only freeing the hinge edge of the doorfrom the flange 13, but so loosening the hinge connection of the door asto make it freely swing into the open position.

Copies of this Although the drawings and above specification disclosethe best mode in which I have contemplated embodying my invention, Idesire to be not limited to the details of such disclosure, for manychanges in form and construction may be made, as circumstances requireor experience suggests, without departing from the spirit of theinvention, within the scope of the appended claims.

I claim:

1. A silo door attaching means comprising, in combination with a silodoor frame and door, hinge means, including longitudinally slidablewedge shaped hinge pins, connecting one side of said door to said frameand locking means, including longitudinally slidable locking wedges, forlocking the other side of said door to said frame, said hinge pins andlocking wedges adapted to cooperate to draw the door into sealingcontact with said frame when said door is closed and said pins andwedges are driven taut.

2. A silo door attaching means comprising, in combination with a silodoor frame and door, hinge means, including wedge shaped hinge pinsdisposed with their smaller ends upward, connecting one side of saiddoor to said frame, and locking means, including locking wedges disposedwith their smaller ends downward, for looking the other side of saiddoor to said frame, said hinge pins and locking wedges adapted tocooperate to draw the door into sealing contact with said frame whensaid door is closed and said pins and wedges are driven taut, and saidhinge pins adapted to drop by gravity to ease the hinge connection whensaid door is opened.

3. In a construction of the character described, in combination with adoor frame and door, wedge-operable hinging means connecting said doorto said frame and comprising eye or knuckle members connected to saiddoor frame and door respectively and a wedge shaped hinge pin connectingsaid eye or knuckle members and adapted, when driven taut, to draw saiddoor toward said frame. V

In testimony that I claim the above, I have hereunto subscribed my namein the presence of two witnesses.
